HF 509 OPEN CHANNEL AND CLOSED CHANNEL FLOW
GENERAL DESCRIPTION

This is a floor standing open channel which can be quickly converted into a closed channel for studying both open and closed channel flow.

The channel has transparent side walls with tanks at both ends for supplying water to and receiving water from the channel. Each tank has a flow control valve to control flow and water level in the channel. The inlet tank has a stilling arrangement. A removable lid is placed on top of the open channel to convert it to a closed channel. The mid section of the channel bed is adjustable for demonstration of Bernoulli theorem in closed conduit flow.

Accessories and measuring instruments are provided for the flow study.
